The Glenmuckloch Pumped Storage Scheme

This article on the BBC is entitled Glenmuckloch Opencast Mine Hydro Energy Scheme Approved.

  • It appears to be capable of generating 400 MW.
  • Energy storage capability appears to be 1.6 GWh.
  • It is to be built in a disused opencast coal mine.

It is only a small scheme, but it does seem to have planning approval.

The Scheme has a web page, which is entitled Glenmuckloch Pumped Storage Hydro

  • It is being promoted by Buccleuch and 2020 Renewables and respected consultants; Arup has produced this Non-Technical Summary.
  • The Non-Technical Summary is a very professional document and an interesting read.
  • 2020 Renewables are now part of Forsa Energy.
  • It is certainly an interesting way of removing the remains of an opencast coal mine.

According to this article on the BBC, which is entitled Buyer Sought For £250m Hydro Scheme At Glenmuckloch, the project now appears to be for sale.

Whether it will sell will depend on the cost of realising the scheme, the finance and how much the scheme will earn.


This project appears to have stalled, but I do like the idea of using a disused mine to store energy and the engineering behind the project.

  2. is the BBC’s report. It seems quite unusual, as there’s also a wind farm and some kind of battery storage planned. It’s also reasonably accessible, just a few miles from Kirkconnel station.
